In a food processor, add parsley, lemon juice, crushed red pepper, salt, sugar, cumin and garlic - pulse until finely minced. Turn processor on and slowly drizzle in oil and broth through food chute and process until well combined, stopping to scrape down the bowl as needed.

To prepare the steak

Rub both sides of steak evenly with garlic - season with salt and pepper. Place steak onto the grill and cook until desired degree of doneness, about 8 to 10 minutes for medium-rare, turning halfway through. Transfer steak to a plate - cover and let rest 5 to 10 minutes. Thinly slice the steak diagonally across the grain and serve with sauce.
